smtp: fix for server doesn't support starttls extension Currently we only support enabling TLS by using SMTP STARTTLS extension. But not all the servers support it. With this patch, user can choose which way to enable TLS: * Default: tls = none port = 25 * To use STARTTLS: tls = starttls port = 465 * To use SMTP over SSL: tls = smtps port = 465 To keep backward compatibility, when tls = true, we use STARTTLS to enable TLS.

avoid .split() in for loops and use tuples instead split can be more readable for longer lists like the list in dirstate.invalidate. As dirstate.invalidate is used in wlock() and therefoe used heavily, I think it's worth avoiding a split there too.

hgweb: added revision date to annotate line data The only revision information yielded by the annotate view was the revision number itself. The patch allows the use of per-line revision dates in the corresponding templates.

opener: forbid paths ending with directory separator (issue2507) If Linux is asked to open a filename with a trailing directory separator, e.g. "foo/", the open fails with EISDIR. On AIX, the open succeeds, opening file "foo". This causes test-mq-qnew to fail on AIX. Fix by adding 'ends with directory separator' to the conditions checked by the path auditor. Change test to expect auditor fail message.

record: clean up command table The --force option to qnew has become a no-op, so qrecord doesn't need to use it. This allows record's command table to be simplified; in the process of doing so, this patch also cleans up the cmdtable visually.
